Figure 4: Expression level of apoptosis relevant proteins. (a) Western blot identified the expression level of apoptosis relevant proteins: Bax, Bcl-2, and caspase-3 in the spinal cord after 48 hours of reperfusion. (b) Compared with the Sham group, the IR group showed a significant increase of Bax, caspase-3 but decrease of Bcl-2. Compared with the IR group, the UTI + IR group demonstrated a significant decreased of Bax and caspase-3 but increase of Bcl-2. Compared with IR group (). Compared with Sham group (). Values are the means ± SD, per group.
